Carrie Underwood and husband Mike Fisher delivered their baby boy into the world last week. On Tuesday, March 3, the singer announced the birth of Isaiah Michael Fisher by tweeting an adorable picture.

Isaiah Michael Fisher was born on February 27. “Tiny hands and tiny feet ... God has blessed us with an amazing gift!” Underwood tells fans via social media. Fisher retweeted soon after.

The birth ends speculation as to when Underwood would deliver, and what she would name the couple’s first child. The "Little Toy Guns" singer had said she was going to wait to meet him before deciding on what she’d call him. The proud Christian chose a Biblical name, in addition to her husband’s name as a middle name.

This is the first child for Fisher and Underwood. The country star has been protective of some of the details, but also included fans and media by openly talking about singing to the unborn child and what traits of Fisher's she hoped he'd get. The 31-year-old has often stepped out in public, proudly showing off her baby bump. She even took the CMA Awards stage to reveal the gender!
